X++ Code Optimization

X++ Code Optimization Following are the coding tips to improve your Axapta system's performance: 1.  Smart Joins  : Try to Use Joins instead of nested while loop wherever possible. 2.  Select Statement  : Mention the field names in the select statement instead of fetching        entire row , this will reduce data amount to transfer from database.     e.g " Select ItemId from inventTable " 3.  Display Methods  : Make sure that generic display methods should be moved at table          level and cached by using"Formdatasource.cacheAddmethod".  4.  Local caching  : Use Variables for storing the constantly used calculated values in loop ,        by doing so you can reduce the calls to the database and different layers. 5.  Monitor the Database Calls  : For bulk records updation, deletion,   ...
